Description

Tarjeta multicapa de material termoplastico y procedimiento de securizaci6n de tarjeta multicapa. Multilayer card of thermoplastic material and procedure for securing multilayer card.

La presente invenci6n concierne a una tarjeta multicapa de material termoplastico utilizable especialmente como soporte de datos. Una tarjeta de este tipo puede servir, por ejemplo, para justificar la identidad del tenedor de la 5 tarjeta o para controlar el acceso a un lugar. La invenci6n tiene igualmente por objeto un procedimiento de securizaci6n de una tarjeta multicapa utilizable, por ejemplo, como soporte de datos. The present invention relates to a multilayer card made of thermoplastic material especially useful as data carrier. Such a card can be used, for example, to justify the identity of the cardholder or to control access to a place. The invention also has as its object a method of securing a usable multilayer card, for example, as data support.

Antecedentes de la invencion Background of the invention

Se conocen tarjetas multicapa que comprenden una capa de coraz6n que forma el cuerpo de la tarjeta, una capa impresa sobre la cual figuran los datos y que se extiende sobre la capa de coraz6n, y una capa transparente de Multilayer cards are known which comprise a heart layer that forms the card body, a printed layer on which the data appears and which extends over the heart layer, and a transparent layer of

10 protecci6n que se extiende sobre la capa impresa. La capa de coraz6n y la capa de protecci6n se realizan en general a partir de tereftalato de polietileno que es un material resistente a las agresiones exteriores y relativamente poco costoso. La capa impresa se realiza en policloruro de vinilo que es un material particularmente bien adaptado a la impresi6n. 10 protection that extends over the printed layer. The heart layer and the protection layer are generally made from polyethylene terephthalate which is a material resistant to external aggressions and relatively inexpensive. The printed layer is made of polyvinyl chloride which is a material particularly well suited to printing.

Una tarjeta de este tipo se realiza por laminado. No obstante, con este procedimiento, la adhesi6n de la capa de A card of this type is made by rolling. However, with this procedure, the adhesion of the layer of

15 protecci6n de tereftalato de polietileno sobre la capa impresa de policloruro de vinilo es relativamente debil de modo que existe un riesgo de que una persona no autorizada despegue la capa de protecci6n de la capa impresa para falsificar los datos que figuran en esta ultima. The protection of polyethylene terephthalate on the printed polyvinylchloride layer is relatively weak so that there is a risk that an unauthorized person will take off the protective layer from the printed layer to falsify the data contained in the latter.

Para obviar este inconveniente, es conocido el recurso de realizar una capa de protecci6n fragmentada. La capa de protecci6n no puede retirarse entonces de una sola pieza, lo que complica su retirada y su recolocaci6n. No To obviate this inconvenience, the resource of making a fragmented protection layer is known. The protective layer cannot then be removed in one piece, which complicates its removal and repositioning. Do not

20 obstante, esta fragmentaci6n complica igualmente la fabricaci6n de la tarjeta. 20 However, this fragmentation also complicates the manufacture of the card.

El documento US 4313984 describe una tarjeta multicapa que comprende una capa de protecci6n y una capa de coraz6n. US 4313984 describes a multilayer card comprising a protection layer and a heart layer.

Objeto de la invencion Object of the invention

Un objeto de la invenci6n es proponer un medio que haga mas diffcil la falsificaci6n de los datos sin complicar 25 excesivamente la fabricaci6n de la tarjeta. An object of the invention is to propose a means that makes the falsification of the data more difficult without unduly complicating the manufacture of the card.

Asf, la zona de uni6n reforzada se opone al despegue de las dos capas. Ventajosamente, la uni6n reforzada tiene una resistencia mecanica superior a la de al menos una de las capas. Asf, durante una tentativa de despegue, esta Thus, the reinforced junction zone opposes the takeoff of the two layers. Advantageously, the reinforced joint has a mechanical strength greater than that of at least one of the layers. Thus, during an attempt to take off, this

30 capa se deteriora antes de que ceda la uni6n reforzada. El deterioro de la capa impide su recolocaci6n y revela la tentativa de falsificaci6n. The layer deteriorates before the reinforced joint yields. The deterioration of the layer prevents its repositioning and reveals the attempt of falsification.

Segun un modo de realizaci6n particular, cuando una capa impresa se extiende entre la capa de protecci6n y la capa de coraz6n, la zona de uni6n reforzada se extiende a traves de la capa impresa entre la capa de protecci6n y la capa de coraz6n. According to a particular embodiment, when a printed layer extends between the protection layer and the heart layer, the reinforced joining zone extends through the printed layer between the protection layer and the heart layer.

35 Asf, cuando la uni6n entre la capa impresa y la capa de protecci6n o la capa de coraz6n es relativamente debil despues del laminado, el medio de uni6n reforzado establece una solidarizaci6n directa de la capa de protecci6n y de la capa de coraz6n. Thus, when the bond between the printed layer and the protection layer or the heart layer is relatively weak after the laminate, the reinforced joining means establishes a direct solidarity of the protection layer and the heart layer.

Ventajosamente entonces, las capas de protecci6n y de coraz6n son de un mismo material termoplastico o de materiales soldables uno con otro, y al menos la capa de protecci6n comprende una porci6n que atraviesa la capa Advantageously then, the protective and core layers are made of the same thermoplastic material or of weldable materials with each other, and at least the protective layer comprises a portion that crosses the layer

40 impresa y esta soldada a una porci6n correspondiente de la capa de coraz6n. 40 printed and is welded to a corresponding portion of the heart layer.

La uni6n reforzada se realiza entonces simplemente por soldadura. The reinforced joint is then made simply by welding.

De preferencia, cuando la tarjeta comprende al menos dos bordes contiguos que forman un angulo entre ellos, la zona de uni6n reforzada esta dispuesta en la proximidad de la intersecci6n de los dos bordes. Preferably, when the card comprises at least two contiguous edges that form an angle between them, the reinforced joint zone is arranged in the vicinity of the intersection of the two edges.

En las tarjetas de la tecnica anterior que comprenden dos bordes contiguos, es mas facil despegar las dos capas In prior art cards comprising two contiguous edges, it is easier to peel off the two layers

45 una de otra a partir de la intersecci6n de los dos bordes. El posicionamiento de la zona de uni6n reforzada en la proximidad de la intersecci6n de los dos bordes de la tarjeta segun la invenci6n permite limitar el posible despegue con un numero limitado de zonas de uni6n reforzada. 45 from one another from the intersection of the two edges. The positioning of the reinforced junction zone in the vicinity of the intersection of the two edges of the card according to the invention makes it possible to limit the possible takeoff with a limited number of reinforced junction zones.

La invenci6n tiene igualmente por objeto un procedimiento de securizaci6n de tarjeta multicapa segun la The invention also has as its object a multilayer card security procedure according to the

reivindicaci6n 5. claim 5.

Otras caracterfsticas y ventajas de la invenci6n resultaran de la lectura de la descripci6n que sigue de un modo de realizaci6n particular no limitativo de la invenci6n.

Descripcion detallada de la invencion Detailed description of the invention

La invenci6n se describe aquf en aplicaci6n a una tarjeta que forma un soporte de datos de identificaci6n del portador de la tarjeta. Puede utilizarse una tarjeta de este tipo con fines de verificaci6n de identidad o de control de acceso a un local. La invenci6n es igualmente aplicable a tarjetas bancarias, tarjetas de telefono o cualquier otra tarjeta destinada a soportar datos. The invention is described herein in application to a card that forms a carrier of cardholder identification data. A card of this type may be used for the purpose of identity verification or access control to a location. The invention is equally applicable to bank cards, phone cards or any other card intended to support data.

Los datos pueden imprimirse sobre la tarjeta de manera directamente legible y/o estar contenidos en una pista magnetica, un circuito integrado o un c6digo de barras legibles por medios de lectura dedicados. The data can be printed on the card in a directly readable way and / or be contained in a magnetic track, an integrated circuit or a readable bar code by dedicated reading means.

Con referencia a las figuras, la tarjeta, generalmente designada 1, es multicapa y tiene un contorno rectangular. With reference to the figures, the card, generally designated 1, is multilayer and has a rectangular contour.

La tarjeta 1 comprende una capa de coraz6n 2, de tereftalato de polietileno (PET) que tiene caras 3, 4 sobre las cuales se extienden capas impresas 5, 6 de policloruro de vinilo (PVC). Cada capa impresa 5, 6 esta recubierta de una capa de protecci6n 7, 8 de tereftalato de polietileno. The card 1 comprises a heart layer 2, of polyethylene terephthalate (PET) having faces 3, 4 on which printed layers 5, 6 of polyvinyl chloride (PVC) are spread. Each printed layer 5, 6 is coated with a protective layer 7, 8 of polyethylene terephthalate.

Sobre las caras 3, 4 de la capa de coraz6n 2 pueden imprimirse una decoraci6n e informaciones generales relativas, por ejemplo, a la autoridad o al organismo que ha suministrado la tarjeta. On the faces 3, 4 of the heart layer 2, a decoration and general information can be printed, for example, to the authority or agency that supplied the card.

Sobre la capa impresa 7 estan impresos, por ejemplo, datos personales del portador de la tarjeta, tales como, aquf, su apellido, nombre, direcci6n y una foto de este o cualquier otro dato que permita su identificaci6n. Pueden imprimirse tambien sobre esta capa informaciones que conciernen a la extensi6n de los derechos conferidos por la tarjeta, una fecha de expiraci6n de la tarjeta, un holograma de securizaci6n, etc. Sobre la capa impresa 8 se imprimen, por ejemplo, informaciones que conciernen al organismo que ha suministrado la tarjeta o un c6digo de barras o cualquier otro tipo de informaciones. On the printed layer 7 are printed, for example, personal data of the cardholder, such as, here, his last name, name, address and a photo of this or any other data that allows his identification. Information concerning the extension of the rights conferred by the card, an expiration date of the card, a security hologram, etc. can also be printed on this layer. On the printed layer 8, for example, information concerning the body that supplied the card or a bar code or any other type of information is printed.

Las capas de protecci6n 7, 8 son resistentes a las agresiones exteriores y aseguran una protecci6n de las informaciones impresas sobre las capas impresas 5, 6 contra un borrado o una alteraci6n debido a estas agresiones. The protective layers 7, 8 are resistant to external aggressions and ensure protection of the printed information on the printed layers 5, 6 against erasure or alteration due to these aggressions.

La tarjeta 1 comprende ademas zonas de uni6n reforzada 9 que se extienden a traves de la capa impresa 5 entre la capa de coraz6n 2 y la capa de protecci6n 7. Las zonas de uni6n reforzada 9 se extienden aquf en la proximidad de la intersecci6n 10 de los bordes contiguos de la tarjeta (es decir, aquf, en las cuatro esquinas de la tarjeta 1), alrededor de la fotograffa y sobre el conjunto de la superficie de la tarjeta 1 en distribuci6n regular. The card 1 further comprises reinforced junction zones 9 that extend through the printed layer 5 between the core layer 2 and the protective layer 7. The reinforced junction zones 9 extend here in the vicinity of the intersection 10 of the contiguous edges of the card (that is, here, in the four corners of the card 1), around the photograph and on the whole surface of the card 1 in regular distribution.

Cada zona de uni6n reforzada 9 esta constituida por una porci6n 11 de la capa de protecci6n 7 que atraviesa la capa impresa 5 y esta soldada a una porci6n correspondiente 12 de la cara 3 de la capa de coraz6n 2. Each reinforced junction zone 9 is constituted by a portion 11 of the protective layer 7 that passes through the printed layer 5 and is welded to a corresponding portion 12 of the face 3 of the heart layer 2.

Las zonas de uni6n reforzada 9 pueden realizarse durante la fabricaci6n de la tarjeta o despues de que la tarjeta se haya fabricado en el marco de un procedimiento de securizaci6n. Reinforced joining areas 9 can be made during the manufacture of the card or after the card has been manufactured within the framework of a security procedure.

Durante la fabricaci6n de la tarjeta, se realiza de forma en sf conocida un laminado de las capas 2, 5, 6, 7 y 8 unas sobre otras para asegurar una solidarizaci6n de dichas capas. Las capas 2, 5, 6, 7, 8 pueden presentarse en forma de placas o de bandas, en las cuales estan delimitados varios emplazamientos de tarjetas que se recortaran a continuaci6n para individualizar las tarjetas. Es contemplable igualmente una fabricaci6n en la unidad. La impresi6n de las tarjetas 2, 5 y 6 se realiza aquf de forma previa al laminado. During the manufacture of the card, a laminate of layers 2, 5, 6, 7 and 8 is carried out in a known manner on one another to ensure a solidarity of said layers. Layers 2, 5, 6, 7, 8 can be presented in the form of plates or bands, in which several locations of cards that are then cut to individualize the cards are delimited. A manufacturing in the unit is also contemplated. The printing of cards 2, 5 and 6 is done here prior to lamination.

Despues del laminado, se procede a la securizaci6n de la tarjeta individualizada o, simultaneamente, de varias tarjetas. After lamination, the individualized card or, simultaneously, several cards are secured.

Se efectua la etapa de realizar localmente uniones suplementarias entre la capa de coraz6n 2 y la capa de protecci6n 7. Las uniones suplementarias se forman directamente entre la capa de coraz6n 2 y la capa de protecci6n 7 a traves de la capa impresa 5. Estas uniones suplementarias forman las zonas de uni6n reforzada 9 descritas anteriormente. The step of making supplementary joints locally between the heart layer 2 and the protection layer 7 is carried out locally. The supplementary joints are formed directly between the heart layer 2 and the protection layer 7 through the printed layer 5. These unions supplementary form the reinforced junction zones 9 described above.

Estas uniones se realizan por soldadura, por medio de un punz6n calentador a fin de prensar y soldar una contra otra las porciones enfrente de la capa de coraz6n 2 y de la capa de protecci6n 7. Los parametros de la soldadura, la temperatura de calentamiento y la presi6n, en particular, se eligen a fin de provocar un reblandecimiento de la capa impresa 5 de tal manera que las porciones 10, 11 a soldar puedan ponerse en contacto una con otra a traves de la capa impresa 5 cuyo material fluye bajo la presi6n ejercida por el punz6n calentador. These joints are made by welding, by means of a heating punch in order to press and weld against each other the portions in front of the heart layer 2 and the protection layer 7. The welding parameters, the heating temperature and The pressure, in particular, is chosen in order to cause a softening of the printed layer 5 so that the portions 10, 11 to be welded can contact each other through the printed layer 5 whose material flows under the pressure exerted by the heater punch.

5 Se constata que esta operaci6n deja una deformaci6n plastica superficial sobre la cara externa de la capa de protecci6n 7. Las zonas de uni6n reforzada 9 pueden organizarse entonces segun un motivo que asegure el mismo una funci6n de securizaci6n. De la misma manera, el punz6n calentador puede presentar una huella que tenga la forma de un sello para realizar un marcado de la cara externa de la capa de protecci6n 7. 5 It is found that this operation leaves a superficial plastic deformation on the outer face of the protective layer 7. The reinforced joining areas 9 can then be organized according to a motive that ensures a securing function itself. In the same way, the heating punch may have a fingerprint in the form of a seal to mark the outer face of the protective layer 7.

El procedimiento de securizaci6n conforme a la invenci6n puede utilizarse, por ejemplo sobre placas o bandas que 10 reagrupan varios emplazamientos de tarjeta o sobre una tarjeta multicapa laminada ya realizada. The securing process according to the invention can be used, for example on plates or bands that regroup several card locations or on a laminated multilayer card already made.

Por supuesto, la invenci6n no esta limitada al modo de realizaci6n descrito y se pueden aportar aquf variantes de realizaci6n sin salir del marco de la invenci6n tal como se define por las reivindicaciones. Of course, the invention is not limited to the embodiment described and variants of embodiment can be provided here without departing from the scope of the invention as defined by the claims.

En particular, pueden practicarse igualmente uniones reforzadas entre la capa de coraz6n 2 y la capa de protecci6n 8 o entre capas internas de la tarjeta. In particular, reinforced joints can also be made between the heart layer 2 and the protection layer 8 or between inner layers of the card.

15 Ademas, el numero de capas de la tarjeta puede ser diferente del del modo de realizaci6n descrito. 15 In addition, the number of layers of the card may be different from the described embodiment.

Asf, la invenci6n se aplica igualmente a las tarjetas multicapas que comprenderfan una capa de coraz6n 2 sobre la cual se imprimen las informaciones a proteger y que estarfan recubiertas directamente por capas de protecci6n. Thus, the invention also applies to multilayer cards that would comprise a layer of heart 2 on which the information to be protected is printed and that would be directly covered by layers of protection.

Ademas, la uni6n reforzada puede realizarse por soldadura termica como se describe anteriormente, por soldadura con ultrasonidos, laser, fricci6n o, qufmicamente, por medio de disolventes. Puede utilizarse igualmente una cola o, In addition, the reinforced joint can be made by thermal welding as described above, by welding with ultrasound, laser, friction or, chemically, by means of solvents. A tail can also be used or,

20 mas generalmente, un adhesivo. 20 more generally, an adhesive.

Por lo demas, los materiales utilizados pueden ser diferentes de los descritos. En el caso del modo de realizaci6n por soldadura, los materiales de las capas de coraz6n y de protecci6n, si bien son diferentes, son soldables uno con otro. Otherwise, the materials used may be different from those described. In the case of the welding mode, the materials of the heart and protective layers, although different, are weldable with one another.
